@SlackerMomMD, I did something similar yesterday with my college-age D, her friend, and my sophomore D. There were 12 eggs, and I put varying ranges of money in the eggs. I told them this beforehand, and suggested they decide before the hunt whether to pool their findings, whether it was finder take all, etc. They decided to pool their egg booty and that each would stop after finding 4 eggs. It was fun for me and for them.
